The Spice That Prevents Fluoride From Destroying Your Brain

Fluoride is found everywhere today, fromantibiotics to drinking water, no stick pans to toothpaste, making exposure inevitable. All the more reason why new research proving this common spice can prevent fluoride damage is so promising!

Fluoride’s neurotoxicity has been the subject of academic debate for decades, and now a matter of increasingly impassioned controversy among the general public, as well.

Now, a new study published in the Pharmacognosy Magazine titled, “Curcumin attenuates neurotoxicity induced by fluoride: An in vivo evidence,” adds experimental support to the suspicion that fluoride is indeed a brain-damaging substance, also revealing that a natural spice-derived protective agent against the various health effects associated with this compound is available.

The study was authored by researchers from the Department of Zoology, University College of Science, M.L. Sukhadia University, Udaipur, India, who have spent the past decade investigating the mechanisms through which fluoride induces severe neurodegenerative changes in the mammalian brain, particularly in cells of the hippocampus and cerebral cortex.[i][ii]

The study opens by describing the historical backdrop for concern about fluoride’s significant and wide ranging toxicity:

“Fluoride (F) is probably the first inorganic ion which drew attention of the scientific world for its toxic effects and now the F toxicity through drinking water is well-recognized as a global problem. Health effect reports on F exposure also include various cancers, adverse reproductive activities, cardiovascular, and neurological diseases.[1,2]“

The study focused on fluoride induced neurotoxicity, identifying excitoxicity (stimulation of the neuron to the point of death) and oxidative stress as the two main drivers of neurodegeneration. It has been observed that subjects with the condition known as fluorosis, a mottling of tooth enamel caused by excessive exposure to fluoride during tooth development, also have neurodegenerative changes associated with a form of oxidative stress known as lipid peroxidation (rancidity).

Excess lipid peroxidation in the brain can lead to a decrease in total brain phospholipid content. Owing to these well-known mechanisms of fluoride associated neurotoxicity and neurodegeneration, the researchers identified the primary polyphenol in the spice turmeric — known as curcumin – as an ideal agent worth testing as a neuroprotective substance.

Previous research on curcumin indicates that it is capable of activing as an antioxidant in 3 distinct ways by protecting against: 1) singlet oxygen 2) hyrodxyl radicals and 3) superoxide radical damage. Also, curcumin appears to raise endogenous glutathione production in the brain, a major antioxidant defense system.

In order to assess the neurotoxic effects of fluoride and prove curcumin’s protective role against it, researchers randomly divided up mice into four groups, for 30 days:

1. Control (no fluoride)

2. Fluoride (120 ppm): fluoride was given in distilled water drinking water without restriction.

In order to ascertain the effect of treatment, the researchers measured the malondialdehyde (MDA) content in the brains of the different treated mice. MDA is a well-known marker of oxidative stress/damage.

“Our study thus demonstrate that daily single dose of 120 ppm F result in highly significant increases in the LPO [lipid peroxidation, i.e. brain rancidity] as well as neurodegenerative changes in neuron cell bodies of selected hippocampal regions. Supplementation with curcumin significantly reduce the toxic effect of F to near normal level by augmenting the antioxidant defense through its scavenging property and provide an evidence of having therapeutic role against oxidative stress mediated neurodegeneration.”

Discussion

This is far from the first study to demonstrate curcumin’s remarkable brain-saving properties.

Considering the many chemical insults we face on a daily basis in the post-industrial world, turmeric may very well be the world’s most important herb, with over 600 evidence-based health applications.

While "Flavor" is very subjective, and each country that grows mangoes is very nationalistic, these are the mango varieties that are the most sought after around the world because of sweetnesss (Brix) and demand.The Chaunsa has a Brix rating in the 22 degree level which is unheard of!Carabao claims to be the sweetest mango in the world and was able to register this in the Guiness book of world records.Perhaps it is time for a GLOBAL taste test ???

Mangaluru: Vagaries of nature is expected to take a toll on the production of King of Fruits - Mango - in Karnataka this year. A combination of failure of pre-monsoon showers at the flowering and growth stage and spike in temperature in mango growing belt of the state is expected to limit the total production of mango to an estimated 12 lakh tonnes in the current season as against 14 lakh tonnes in the last calendar year.

However, the good news for fruit lovers is that this could see price of mangoes across varieties decrease marginally by 2-3%. This is mainly on account of 'import' of the fruit from other mango-growing states in India, said M Kamalakshi Rajanna, chairperson, Karnataka State Mango Development and Marketing Corporation Ltd.

Karnataka is the third largest mango-growing state in India after Uttar Pradesh and Maharashtra.

Experts at the Birbal Sahni Institute of Palaeobotany (BSIP) here have traced the origin of mango to the hills of Meghalaya, India from a 65 million year-old fossil of a mango leaf.

The earlier fossil records of mango (Mangifera indica) from the Northeast and elsewhere were 25 to 30 million years old. The 'carbonized leaf fossil' from Damalgiri area of Meghalaya hills, believed to be a mango tree from the peninsular India, was found by Dr R. C. Mehrotra, senior scientist, BSIP and his colleagues.

After careful analysis of the fossil of the mango leaf and leaves of modern plants, the BISP scientist found many of the fossil leaf characters to be similar to mangifera.

An extensive study of the anatomy and morphology of several modern-day species of the genus mangifera with the fossil samples had reinforced the concept that its centre of origin is Northeast India, from where it spread into neighbouring areas, says Dr. Mehrotra.
